Can Microorganisms Be A Solution To The World’s Energy Problems?

Microorganisms once reigned supreme on the Earth, thriving by filling every nook and cranny of the environment billions of years before humans first arrived on the scene. Now, this ability of microorganisms to grow from an almost infinite variety of food sources may play a significant role in bailing out society from its current energy […]

Report Confirms Drilling, Not Earthquake, Caused Java Mud Volcano

A mud volcano that has caused millions of dollars worth of damage was caused by the drilling of a gas exploration well, an international team of scientists has concluded.
The two-year old mud volcano, Lusi, is still spewing huge volumes of mud and has displaced more than 30,000 people.
The most detailed scientific analysis to date disproves […]

Halting Methane Squanderlust

The pipes that rise from oil fields, topped with burning flames of natural gas, waste fossil fuels and dump carbon dioxide into the air. In new work, researchers have identified the structure of a catalytic material that can turn methane into a safe and easy-to-transport liquid. The insight lays the foundation for converting excess methane […]

High Fuel Prices Could Slash U.S. Emissions

High gasoline prices could lead to a dramatic saving in US greenhouse-gas emissions. That’s the conclusion of economists in the US, who suggest high fuel prices are turning consumers off SUVs and onto smaller, more fuel-efficient vehicles.
What’s more, car owners are predicted to cut back on driving in order to save money. Together, these changes […]
